When you exercise, you feel good. Not only does exercise increase your attractiveness, thereby, increasing your self-esteem, but exercise also directly fights depression. Depression is related to low levels of certain neurotransmitters like serotonin and norepinephrine. Exercise, however, tends to increase the concentration of these neurotransmitters and also stimulates the release of endorphins, the feel-good neurotransmitter that resembles opiates in their ability to block feelings of pain.
